Burkert Type 8652 AirLINE is a valve island especially developed for process automation requirements. New diagnostic functions can be visualised on the LC display, both in clear text as well as symbols. This makes it easy to relate to the shown messages and helps to save time during start-up and maintenance. Furthermore, the diagnostic message is also available at the controller, enabling a fast overview of the plant status. The hardware is optimised for installation at the bottom of the control cabinet, though installation on a standard rail is also possible. Key pneumatic functions ensure increased process reliability; for instance, check valves in the exhaust air ducts make sure there is no unplanned actuation due to pressure peaks.

AirLINE Quick

AirLINE Quick considerably reduces the use of components in the control cabinet. With the AirLINE Quick Adapter, the valve terminal is adapted directly to the control cabinet floor or control cabinet wall.

Advantages:

• Reduced space requirement in the control cabinet
• This makes it possible to use more compact control cabinets
• Reduced installation effort due to hose connections directly at the bottom of the control cabinet

Pin	Colour	Assignment
1	Red	24 V DC
2	White	CAN_H (büS connection)
3	Green	SHIELDING
4	Blue	CAN_L (büS connection)
5	Black	GND

Power supply for pneumatic valves

The interface plate has a 2-pin spring-loaded terminal to which the pneumatic valves’ power supply is connected.

Clip	Colour	Assignment
1	Red	AUX 24 V
2	Black	GND

Product Design and Assembly

Electronic module with digital inputs (optional)

The digital inputs are supplied (24 V) by the electronic module. Current is limited to maximum 30 mA per digital input. Standard 3-wire sensors and 2-wire sensors with voltages between 10…30 V as well as mechanical limit switches can be used.

Valves Type 6534 for safety-related shut-off, SIA variant (optional)

Type 6534 valves are equipped with additional connection terminals. A valve circuit can therefore be interrupted by an external switch. Manual override is not required for these valve variants. To use the shut-off function, connect the terminal to a potential-free contact (mechanical switch or relay).

Example configuration

Safety Instructions for Hazardous Locations

Voltage Hazards

• Before working on the device or system, switch off the power supply. Secure against reactivation.
• In an existing explosive atmosphere, the connection terminals for 24 V supply, SIA, EVS, and digital inputs may only be plugged in or unplugged when the power is switched off.
• The Hot Swap function is prohibited in an existing explosive atmosphere.

Electrostatic Charge

• Take appropriate measures to ensure that no electrostatic charge can build up in the potentially explosive area.
• Only clean the device surface by wiping it gently with a damp or antistatic cloth.

Special Conditions for Safe Use

• For explosion protection type "ec", install the device in an enclosure that complies with the applicable requirements of EN/IEC 60079-0 and EN/IEC 60079-7, with a degree of protection of at least IP54.
• For explosion protection type "tc" (dust), install the device in an enclosure that complies with EN/IEC 60079-0 and EN/IEC 60079-31, with a degree of protection of at least IP6X.
• Only use the device in an area with a pollution degree of at least 2 as defined in IEC 60664-1.
